that the aspectual classes are simply useful summaries of commonly co-occurring feature combinations, where features are boundedness, duration, and homogeneity (also dynamicity, but we don't cover this in this class);

that the linguistic tests introduced in the chapter target specific features (boundedness, ...), so you typically need to apply several of them to identify a single aspectual class;

that the progressive removes the boundedness of bounded events, and how that interacts with the aspectual class of a predicate in terms of acceptability and ensuing interpretations (section 9.2.5).

Make sure you know how to:

apply the linguistic tests for boundedness, duration, homogeneity of eventualities

and that these tests yield different interpretations that lead to different diagnoses: for instance,

tests for boundedness:

in + time expression targets bounded eventualities. It yields duration of the whole eventuality with accomplishments, unacceptability or repair readings (onset, habituality) with semelfactives as well as with unbounded eventualites (states and processes); see examples (9-12);
